Sometimes a BSOD is not a sign of a software issue but instead points to a hardware problem and might help explain the symptoms of bad system performance. That was the case recently when a user complained that she was having troubles trying to logon. The workstation was amazingly slow (can slow be amazing?) and then blue-screened on her randomly. My co-worker was handling this but he happens to sit right next to me and I jumped in when I heard the words “blue screen”. I unkindly interjected with “Lets get a minidump.” While he chatted her up, I went about getting her IP, connected via the UNC, went into C:\Windows\Minidump and grabbed the last two mini dumps for that day.

Minidumps excite me. To understand why, you need to have come across a great amount of support calls that usually end up trumping first tier technical support. Often times, these issues are too vague to narrow down if you don’t know how to handle a BSOD, and the incident remains open longer than it needs because it can’t be explained or reproduced immediately. The mini dump provides a means to sometimes quickly resolve what might otherwise become an unexplained system problem.

Minidumps are small, too. Between 64 and 256KB, they only record the smallest set of useful information that could help identify why the system stopped unexpectedly so there would be no problem copying from over a WAN. Once copied over to my workstation, I opened with WinDbg, clicked the !analyze -v hyper command. Both dumps produced identical results: Read the rest of this entry »
